Aggressive Throaty Sound. Add a throaty muscle car exhaust note to your 5.0L and improve the exhaust flow at the same time with a MAC Performance Cat-Back exhaust system from AmericanMuscle.

Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

Mac cat back sound really good. So I had BBK long tube header with BBK short x pipe and mac cat back exhaust so install was too bad drive side was pretty much easy than passages side because I had move or adjust muffle, tailpipe and tip chrome end too try get tailpipe in middle of between gas tank and tires so I had need hand with it. So I like it pretty much I can't wait for weather get warmer and beautiful outside to drive my mustang and listen to muffle see what sound like

Bought this for my fathers GT convertible and he wanted something that had no freeway drone but still showed off that V8 growl. So far he’s had it on for a week and loving it. The hardest part was just aligning all the pieces to make the tips sit right but with two people it only took us about 2hrs to install in total.

Great product, Sounds great matched with my Bassani xpipe. I recommend having a someone to help with installation, can be a little annoying at times lining things up by yourself. Other than that I highly recommend this Mac catback exhaust

Great sound, not as loud as my last Mac system but it's still brand new. Fit and finish is decent. My OCD had a hard time lining up the tips to make them true and square with one another as the axle humps seemed to be a little off but nothing two guys couldn't handle. Definitely will buy again if need be.

My 1994 GT Convertible exhaust set up: original manifolds (headers), Bassani catted x-pipe, original cat-back pipes with Flowmaster 40's welded. Tried other mufflers - Borla Pro XS, Dynomax Super Turbos - with the original pipes before installing the Flowmasters. They all sounded terrible, like an old pick up truck, and the drone from the Flowmasters was terrible. I think the exhaust was being choked from the x-pipe (2.5in) to the pipes(2.25in). I don't think it would have mattered what muffler I installed; it was going to sound bad. Did a lot of searching, listening, etc. Wanted to minimize drone and keep the sound somewhat tame. The rep for AMERICANMUSCLE recommended the MAC cat-back. Received it in 2 days. The 3in tail pipes look fantastic. The sound is better than I thought it would be. Drone is minimal. Does not give me a headache. Does not interfere with the radio, although you have to turn it up a notch. And, you can have a conversation at 70mph/2k rpms. At 65mph/1700rpm, you don't hear the mufflers. When you push the throttle through the gears, the 5.0 has an authoritative sound. I had it installed at a shop. Fit is perfect. For the money, there is no better exhaust note!

I can't begin to tell you how happy I am with this system. The Mac catback gave my 5.0 some nice deep tones and low rumble. It isn't overly loud and obnoxious. I can have an enjoyable conversation with passengers and not have to yell back and forth. My hopes is to pair this system with a pro chamber mid pipe and shorty headers. For the money, you can't beat this system.

Easy install. About 2.5 hours start to finish. Sounds very good with bbk o/r h pipe and shorty headers. Pretty straight forward instructions. Had to spend a little extra time with the tips as they are the tear focal point. All in all completely satisfied with my purches. Thanks to the folks at American muscle for sending a product that makes my Cobra sound straight nasty.

Tailpipes wouldn't clear gas tank, I had to retrofit it using my stock tailpipes. Other than that it sounds good but I feel like I wasted my money not being able to use the tails and tips. AM should not advertise it fitting 94-95. First disappointment from AM and hopefully the last

I honestly wanted flowmaster. But helped out a friend and took the Mac off his hands cause of issues with his car. Now that my mufflers blew up I bought a flowmaster set. lets just say I'm taking them off and putting MAC back on. Love the sound lasted many years and will continue to go with MAC EXHAUST

I got this during the black Friday sale because my current catback has seen better days. I purchased based on price and it was so cheap with the sale I could not pass it up. Now, I have heard MAC on many stangs before, and always felt that it was directly comparable to the same chambered tone of a Flowmaster; with just a cheaper price tag. I was correct in my assumptions and the sound is just right for me. I have shorty headers and an O/R H pipe and this 2.5" catback sounds around the same volume as American Thunder, or Pypes Violators.
I have no drone that I can detect, although I do have 4.10 gears which puts the RPM's a bit higher at cruise to where you don't get much drone from 2 and 3 chamber mufflers anyways. I tried to cruise at around 2,000rpms to duplicate the drone I had with my Flowmaster 40 series at that RPM and I do not hear anything, so I am assuming that this exhaust system has no drone issues.
Inside the vehicle the exhaust is very mild, you can have a conversation on speakerphone or hear your radio without a problem. No vibration issues or excessive heat coming into the cabin, I drove for an hour and felt the carpeting and it was not even warm.
The quality of the system is excellent, all welds look great, all mandrel bent and utilizes ball flanges at multiple points to not only make installation over the axle easier, but allow adjustments to be made that on other catback systems may not be feasible.
The system comes with the hardware for the catback itself, you will need to either reuse your existing bolts to mount the catback to your mid pipe, or purchase new hardware. The bolts are 7/16" thread by 2.5-3", or use metric M10, in a good quality stainless. You also will need to either reuse your existing rubber biscuit hangers or purchase new ones as well.
The exhaust tips are clamped on, which I first felt was cheap and tacky, but I was wrong and I like them. The fact that the tips clamp on allows for some fine adjustments of how deep you want your tips to be, or how much you would like to make them protrude from underneath the car. I managed to get them to protrude roughly the same as stock on my 1995 GT, or about 1.5" with no problem. Just work slow and allow yourself time after install to go back over everything and make adjustments if a part of the exhaust hits the undercarriage or suspension, then when all is well you can re tighten everything.
As far as performance is concerned, I never have noticed any performance gains from catbacks on any car, even if a dyno shows some marginal gain of 5rwhp or so, you can't feel that anyways unless maybe you are the Stig or something. Let's face it, we buy exhaust for a Mustang for sound and to make statements, and this does not disappoint, it is neither too quiet or too loud, won't set off car alarms but it lets you know that you mean business.
I would purchase this system again and recommend to anyone that wants an aggressive tone without the high price tag associated. I also would recommend this exhaust for looks, the 3" stainless tips with a mirror polished finish look great and I can't stop turning back to see my car every time I park it. Thank you American Muscle!

The shop told me that for the most part it went in with only a few hitches. The thing I like is that they were able to have the tips to e tend past the bumper, unlike my last MAC exhaust which ended just short of the back edge. The tips have a great finish.
